It wouldn't solve more than a handful of users issues.
The main reason is because this is for the Amd chipsets only, and it's also only for the graphics card and the software for that.
First off not everyone use AMD graphics chipsets in their computers, there's also the manufacturer nvidia which makes their own graphic processors, but on laptops and smaller motherboards for pcs it runs integrated graphics such as "Intel onboard graphics".
What a graphics card and it's drivers are doesn't even come up and gets explained on the page you linked, might as well use wikipedia or google, maybe even ask anyone that knows. You still find out which GPU you have by running dxdiag or just checking up your computer specs on a site if you know the name, or maybe even the box/papers it came with. The page you linked would probably just be able to find out your Operating system and possible the graphics card if you have an AMD card, but if you don't even know which card you do have this will not help if it fails detecting it as an amd one.
This also requires you to install this amd auto detect software, when you don't really need any software to find out what your computer has.
How you update it varies from the manufacturer, but it's all down to downloading an installer that is the correct one for your graphics card, installing the files, then restart the computer in some cases. Something that isn't plainly explained on this page either unless you browse around in their faq board.
How you know if it needs to be updated only works on that site as mentioned earlier, if it's an amd graphics card, which explained before, not everyone use.
